Write an equation of the circle with center (-9, -6) and diameter 12.

(x+9)^2+(y+6)^2=36

Step-by-step explanation:

The equation of a circle is (x-h)^2+(y-k)^2=r^2 where (h,k) is the given center and r is the radius of the circle.

Given a center of (-9,-6) we have (x+9)^2+(y+6)^2=r^2 so far.

Since the diameter is 12, half of that is the radius which is 6, so the equation of the circle is (x+9)^2+(y+6)^2=36 (as 36 is 6^2)

answer: i think you should do the math and pay attention in class : )

step-by-step explanation:

that is truly what   think but if i get the answer i will
